Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Statamic CMS (Packagist package statamic/cms) versions before 5.73.22 and from 6.0.0-alpha.1 before 6.18.1 are affected. An unauthenticated user can bypass the Glide image proxy's URL validation using an unnormalized IP representation, causing the server to make requests to internal addresses such as loopback, private network, and cloud metadata endpoints. The source says sites that pass user-supplied URLs to Glide are affected and that sites running PHP 8.3 or newer are not. Upgrade to 5.73.22 or 6.18.1.
